The Annalista Saxo ("Saxon annalist") is the anonymous author of an important imperial chronicle, believed to have originated in the mid-12th century at Nienburg Abbey in the Duchy of Saxony.
The chronicle of the "Annalista Saxo" is a collection of dates and facts about the medieval German monarchs (Kings of the Romans) and their Carolingian predecessors, beginning in the year 741 and continued until 1142.
The identity of the chronicler, sometimes identified with Abbot Arnold of Nienburg (d. 1166), has not been conclusively established.
The cover is of brown cow's leather, the spine of vellum, and the content includes 16 ornamental initials.
The original of the "Annalista Saxo" is today in the Bibliothèque nationale de France in Paris.
